RPCS3

V766 An item with the same key '0x120' has already been added. evdev_joystick_handler.h 135

class evdev_joystick_handler final : public PadHandlerBase
{
  const std::unordered_map<u32, std::string> button_list =
  {
    // ....
    { 0x11d               , "0x11d"       },
    { 0x11e               , "0x11e"       },
    { 0x11f               , "0x11f"       },
    { BTN_JOYSTICK        , "Joystick"    }, // <=
    { BTN_TRIGGER         , "Trigger"     }, // <=
    { BTN_THUMB           , "Thumb"       },
    { BTN_THUMB2          , "Thumb 2"     },
    { BTN_TOP             , "Top"         },
    { BTN_TOP2            , "Top 2"       },
    { BTN_PINKIE          , "Pinkie"      },
    // ....
  }
}

At first glance at code, it is not clear which two keys are the same. It turns out that BTN_JOYSTICK and BTN_TRIGGER are Linux API constants that equals 0x120. (https://elixir.bootlin.com/linux/latest/source/include/uapi/linux/input-event-codes.h#L365) BTN_JOYSTICK is the starting value of the joystick signal constant group and BTN_TRIGGER is the very first constant in the list of that group. Therefore, their values are the same.
